摘　　要：晶闸管控制串联电容补偿器(TCSC)是FACTS家族中的第一代可控串联补偿装置,它对电力系统性能的改善有着明显的优越性,但是加入串补装置后,在改善优化系统性能的同时,也给系统带来一些不利影响,使系统线路的潜供电流和恢复电压增大进而影响线路重合闸的成功率。本文阐述了TCSC的基本结构及工作原理,详细分析了加入串补装置对系统的潜供电流和恢复电压的影响,并对其进行归纳总结,得出结论。最后用MATALB中的S imu link仿真软件搭建含TCSC元件的系统模型进行仿真,对仿真得出的潜供电流和恢复电压波形等进行比较,验证了分析所得出的结论。Thyristor controlled series capacitance compensator（TCSC） is the first generation of FACTS family,which can improve the performance of electric power system obviously.With the optimization to improve system performance,also bring some adverse effects to the system.The system secondary arc current and recovery voltage should increase,which affect reclosing of success.This paper expounded the basic TCSC structure and working principle detailed.Analyzed and summarized the influence of the secondary arc current and recovery voltage.Finally,by the Simulink software with MATALB containing TCSC components,build the simulation model to test the analysis results.The simulation results showed that the analysis is correct.
